T0 ALLWHOM IT MAY CONCERN:

Beit known that I, WILLIAM C. GBIMES, of Philadelphia, in the countyof Philadelphia, in lthe State ci' Pennsylvnnimhave invented a new and useful Improvement in Fire-Indicators andI do hereby declare that the following is a full and exact description thereof, reference beinghad to the accompanyingdruwings, and te the letters of reference marked thereon. l

-The object of my improvement is to give to a watchman, or other attendant employed for the purpose, the earliest indication of any re or incipient burning in any room, hall, or building protected by or connected with the apparatus. v

The nature of my invention consists in forming a tubular communication between one closed room ,br-'apartment and any n-umbe!` ofother rooms, halls, or chambers, and in such'a manner a's to have an air-draught through `all the tubes owing into the one closed apartment -or watch-room.

- A' tube, E, runs from the watch-room C to each room, h'all, or chamber A A designen to be protected, and traverses more or lesstof the length or breadth of the apartment in which it terminates, and-is in that parte e -more o r less perforated, in order to render it' less liable to being closed by accident or design, and it may have atrumpet-shuped or iaring termination. The 'tub'emay be'cai'ried alongjthe upper corners oithefupartmenft, or cisewhere next the ceiling, and thence, in the least obtrusiveway, to the watch-room, where it terminates; the orifice being more or less elevated and accessible. Above the watch-room C, rises a chimney or ilue, b, whereby to obtain a .natural or vartificial draught. The latter may be obtained by a iire or stove kept in the watch-room for the purpose,and thus a draught through all the tubes flowing into the watch-room may be4 maintained. Y

Figure 1 is a vertical section or elevation of a series of rooms or chambers` having tubular communications with the watch-room above.

Figure 2 is a vertical transverse section of iig. 1

Like letters of reference being used for the same parte in all the gures.

A A, rooms, halls, or chambers; C C, watch-room; D D, passages; E, connecting or communicatingf tubes; F F,sections of hose; G, water-pipe; Il, well for hose; b, chimney; e e, perforated part of the tubes.

In a suitable or convenient position upon each floor, I place one or more sections of hose F, and pipe of' an aggregate length suiiicient to reach .every room or apartment upon that iloor.- vThese are connected with a water-pipe or some suitable fountain, G, so as to be always ready for use at a momenta warning. The hose, when not yin use, may be dropped in a doubled form into a deep Well or tube, H, or may be wound on a reel.

Use of the apparatus: A watchmanor suitable person occupies t he' \vatch-roomA constantly, and should a re commence in any of the rooms connected by a tube therewith, he will beepprised thereof by the oder of burning. A moments attention at the tubes will determine from what room it emanates, the rooms and tubes being numbered. The watchman at once repairs to the room, being provided with the proper keys, and, with vthehose at hand, he is amply able to quench any incipient burning.

What I claim as my invention, and desire to secure by Letters Patent, is

A series of tubes converging from severall apartments of a house to one apartment, and adapted for the transmission of aeriform uids to this centre, substantially as shown and described, Yand for the purpose set forth.
